That would be not allowed. If time were digital, particles could be like marbles in a jar.

You are overlooking the possibility that those marbles are all identically shaped cubes. No gaps between cubes.

space can not be cubes.

If there were cubes, the vibrations would be different along a diagonal vs. along an axis and we could see the difference.

This is why time is probably quantized and not space.
